If you are planning to visit or is currently in kerala, I strongly prefer that you make a visit to the athirappilly waterfalls near chalkkudy, thrissur.The waterfalls is situated near a forest area, but transportarion facilities are good.it is not the biggest, but still one of the most fascinating waterfalls in india.you may have already seen it in some movirs like ravan.also there are other nearby attractions like ezhattumugham, vazhachal, etc
